ATEN'r WILLIAM DAY, OF BROOKLYN, NEW YORK.

LAM P-SHADE.

SPECIFICATION forming part of Letters Patent No. 256,825, dated April 25, 1882.

Application filed February 25, 1882.

To all whom it may concern Be it known that I,W1LLIAM DAY, ot'Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Adjustable Shades, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates especially to shades for use upon lamps or gas-fixtures, and has for its object the production of a device by which the light may be cut otf by means of one or more adjustable'screens attached to and forming a part of the shade; and it consists essentiallyin locating upon the inner surface of the shade one or more screens or movable slides, which may be pushed up out of sight or drawn down to any desired distance in order to shield the eyes or throw the light downward at an angle; and my invention involves certain novel and useful combinations or arrangements of parts and peculiarities of construction and operation, all of which will be hereinafter first fully described, and then pointed out in the claims.

In the drawings, Figure l is'an elevation of an adjustable shade, showing a screen drawn downward therefrom. Fig. 2 is an interior elevation of one-half of a shade. Fig. 3 is a vertical sectional view through the shade at line a: w of Fig. 2.

Like letters of reference, wherever they occur, indicate corresponding parts in all the figures.

A is the body of the. shade. It may be constructed of tin or other sheet metal, or of porcelain, glass, paper, &o., as my device may be readily applied to shades of any material.

B is a screen, of suitable material, conforming to the contour of the interior of the shade, and fitting nicely thereagainst when pushed upward, as shown in Fig. 2. Screen B is provided at top with projecting ears b,which find a bearing against a strip, (3, attached to the (No model.)

interior of the shade, when the same is pulled down its entire length, as shown in Fig. 1 by the dotted lines; and the ears prevent the screen falling or becoming displaced. Strip 0 presses against the screen with sufficient force to hold it in any position it may he placed. At the lower side of screen B is located a turned edge, D,which fits nicely over the lower edge of the shade and provides ready means for moving the screen.

My improved adjustable shade maybe employed with any kind of light; and, if desired. a number of screens may be used, so that, if desired, the rays of light may be cut ofi' at any point.

Having now fully described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. A lamp-shade of the character herein specified, having one or more movable screens located upon the interior of the body of the shade, adapted antler-ranged to be pushed upward within'the shade or pulled below the edge thereof, substantially as shown. and described.

2. In an adjustable shade of the character heroin specified, the eombination,with the body A of the shade,of a movable screen, B,secured to the interior thereof, and adapted and arranged to be raised or lowered therein, substantially as shown and described.

3. In an adjustable shade, the body A,sereen B, havingears b and turned edge D, and strip 0, attached to the interior of the shade and pressing against said screen B, the whole combined and arranged to operate substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of two witnesses.

WILLIAM DAY.
